Mandarin mania in America

With China’s fast expanding role as a global player, schools in the United States are initiating Chinese “immersion” programmes for its students.

SHE arrived in California from Taiwan as a 16-year-old but wasn’t able to speak in English. Now, at 49, Susan Wang heads a school offering children in the United States a similar experience, plunging them into a “Chinese world”.

And her establishment is part of a rapid expansion of Chinese language “immersion” programmes in the United States, helped notably by Beijing, which is providing low-cost native-speaker teachers to cash-strapped US schools.

Pupils as young as five at her Broadway Elementary School in Venice, west of Los Angeles, take classes entirely in Chinese, in a project so successful that it will be moving into new premises soon.

“The single most exciting thing has to be watching the kids learn Mandarin, and how they learn, and how fast they pick up another language, it’s just amazing,” she said taking a break from her busy day at the local school.

“I didn’t speak English when I came to the US, so when it comes to dual language and language learning ... it’s something close to my heart,” she added.

Chinese immersion programmes are not new in American schools. But China’s rapidly expanding world role has fuelled growing demand for Mandarin language skills, mirroring Washington’s diplomatic pivot across the Pacific.

Mandarin teaching has expanded nationwide over the last decade, in contrast to other foreign languages which have steadily decreased, according to data compiled by the Centre for Applied Linguistics (CAL).
“Mandarin is really taking off ... Chinese is one of the few languages that is becoming increasingly popular, while most other language offerings have not “grown” as much including French, German, and Japanese,” said Nancy Rhodes of the Washington DC-based CAL.

Beijing’s Education Ministry is also helping by sending native speaker teachers effectively for free to work in US schools.

“Schools are of course experiencing huge budget cuts, so the offer of free or low-cost native-speaker teachers from China to teach language classes really looks good,” said Rhodes.

California has been in the forefront, both geographically and historically, ever since huge numbers of Chinese workers helped build the US railroad system. San Francisco and Los Angeles have the biggest Chinese communities after New York.

Traditionally, families with one or both parents from Chinese backgrounds have put children into Mandarin-language schools to bolster their cultural “heritage,” or ability to communicate with grandparents back home.

But increasingly, parents cite economic and career-prospect reasons for making sure that their offspring are able to speak in Chinese.

“I wanted them to have the opportunity to be able to leave the United States if they wished to go and seek employment somewhere else,” said Julie Wang, an Australian who came to the United States when she was 25.

“I did that myself ... I came out here. I think it’s a great opportunity for them to experience different cultures, different ways of life, not just the one that they grew up in,” she added.

In the classroom, the linguistic immersion is total. The walls are plastered with pictures and signs entirely in Chinese and so are the text books, and the teacher will not accept a word of English.

And while some children have a Chinese parent or grandparents, the eager faces around the room are from all backgrounds, from African American and white Caucasian to Latino youngsters.

Many don’t speak a word of Mandarin when they arrive. “At the beginning, it is difficult,” said kindergarten teacher Carol Chan, adding that at first, she had to use a lot of gestures, visual aids and games.

“I use a lot of pictures and ... a lot of music. It is difficult because they don’t understand a word I’m saying. But through physical language and gestures, they really catch on. And they’re having fun with me too!”

First-grader Grace Ehlers says it was tough at first, but now she is equally confident in both languages.

“It’s the same, or maybe a little bit easier in Chinese because my dad speaks many languages and sometimes he teaches me a little bit of it,” she said, when asked to compare classes in English and Mandarin.

The school’s principal says the availability of free Chinese teachers was crucial to Broadway Elementary’s decision to offer the Mandarin language immersion programme.

“I am Chinese, born and raised in Taiwan. But that has nothing to do with why I’m here doing this programme

“The Chinese volunteer teachers were what we were able to get. Had we been able to get free French teachers, or free Spanish teachers, we’d be teaching those,” she added.

According to the centre, there were 74 Mandarin language immersion programmes in the United States in 2008, the last time the data was updated. “I do know that there are more programmes not yet listed,” said Rhodes.

Overall, Spanish has the most immersion programmes, with 45% of the total, followed by French (22%), Mandarin (13%) and Hawaiian, Japanese and German.

“In the past, Chinese has traditionally been taught more on the West Coast and in major cities but we’re seeing more Chinese programmes cropping up all over the country now,” she said.

“Even smaller districts that we work with ... that are starting up elementary school language programmes are considering switching between Spanish and Chinese,” she said, adding that the expansion will likely continue.
“I don’t see the trend slowing anytime soon,” said Rhodes.

Upgrade the standard of education to defrag high cost!



A LARGE section of teenagers will now decide what to do with their lives after receiving their SPM and STPM results.

Decision-time beckons for them as they will ponder whether to pursue a tertiary education, enrol in a skills programme or enter the workforce.

The higher number of those scoring straight As will please them and their parents to no end but the results also show that overall, students did perform poorer than last year.

It's interesting to note that nearly 20% of candidates who sat for the history paper failed and I wonder what will happen to the overall passing rate for SPM students once that subject becomes a compulsory paper for future students. They will need to pass the subject if they were to get their SPM certificate.

While receiving education through government schools is still the most popular route for students in Malaysia, there is a growing number of parents who have chosen that their children study in international schools.

Such schools teach and prepare their students based on the curriculum of other countries, namely the UK, America, Australia and even Singapore.

The rationale for sending their children to those schools would certainly be to enable their children to receive what they perceive is better education.

Sure. Children who make their journey through such schools will be exposed to a different learning system, a different curriculum and the broad-based approach to learning employed by those schools certainly will equip their students to think critically and maybe be more engaging during the learning process.

But the thing is that the allure of giving such an education certainly masks the cost of providing such learning to their children and many who enrolled their children in international or private schools will feel the pinch as they progress through the years.

One friend says that the school where he is sending his two kids to will raise its fees by 40% for the intake of students from September this year.

He is lucky because he doesn't have to feel the brunt of such a steep increase in fees but the annual cost of sending his kids to that school certainly keeps rising faster than the rate of inflation in Malaysia. Plus when they cross a certain year, there is a big bump in the fees he pays.

The thing is that when he first took the plunge to send his kids through the school, it was estimated it will cost him the price of a Mercedes E class. Today, he thinks it's close to RM1mil.

That's basically the cost of sending a student to study medicine overseas, and it's no secret that the cost of education from international schools is far more than what it will be to receive a university degree from a local institution of higher learning.

But that's a business and parents have to fork out huge sums of money if they want their children to go through such an education system. Some may feel it's worth it but parents should really examine what will be the hidden costs of sending their children to international schools.

The top international schools do have a long waiting list and with restrictions to open up such schools lifted, more of such schools will be built and hopefully competitive pressure will mean that fees will be a little more reasonable.

The one drawback of receiving an education from international schools, even though there is a growing number of Malaysians enrolled, is that pupils do not really receive the education that integrates them into the fabric of Malaysian culture.

There are no students from impoverished backgrounds and I don't think you will find them from the broad layers of society. One CEO I met refused to send his two children to a private school. It's not that he cannot afford the fees but it's because he didn't want them to miss out on society's education.

But the higher fees and the clamour for more middle and upper class Malaysians to choose international and private schools should translate to an urgency to raise the quality of education in government schools.

There is a national education blueprint and hopefully the final report on what needs to be done gets implemented fast. Otherwise, there will be a lot of middle class Malaysians who will feel the pinch as they choose to give what they think is a better education for their children.

MAKING A POINTBy JAGDEV SINGH SIDHU

Acting business features editor Jagdev Singh Sidhu wishes the quality of education in government schools was better than what it was like when he was a student.

Measuring your Heart Rate for fitness


Why do you need to know your heart rate? What heart rate zone will give you the absolute BEST results for fat burning from your cardio?

I was recently inspired to write this article on heart rates in relation to fitness due to the numerous questions I have received lately about it, and the importance of knowing what it is, and why. Even though the heart rate is a huge element to achieving an optimal workout, and its been around forever, many individuals do not know what theirs is, or how to measure it, or even to care about it. So I am going to clarify this simple yet important component to fitness. 

Resting, Exercise and Maximum
Heart Rates
 
There are three HR to consider when training to get fit, or as it relates to cardiovascular fitness, as well as your Target Zone. 

The first is the Resting HR. This is your HR when you are not engaging in any physical activity that elevates it, or when you are in a resting state such as sleep. As you become more fit, this number will decrease because your heart and lungs have become stronger. The heart is then able to pump more blood, which is called stroke volume, throughout the body with less effort. The lungs are able to pull in more oxygen, which is called maximum oxygen uptake, with less effort, which means more blood and oxygen to the working muscles makes up the endurance portion of being fit. Having enough oxygen going into the blood keeps the lactic acid out-thus you can sustain a prolonged aerobic workout. 


A normal Resting HR can vary as low as 40 BPM to as high as 100 BPM. 70 BPM is usually the average for a man, and 75 BPM is average for a woman. The Resting HR should be used as an index to improve your cardiovascular fitness level, with a focus on decreasing it. The best time to measure your Resting HR is when you first arise from sleep in the morning. The palpation (beats) of the Radial Pulse is accurately measured in your wrist in line with the base of your thumb. Place the tips of your index and middle fingers over the Radial Artery and apply a light pressure to it. DO NOT USE YOUR THUMB. It has a pulse of it's own. You may count the beats for one full minute to get the HR, or for 30 seconds and multiply by 2 for the number of BPM. 


The Second is the Exercise HR. This is the rate at which your body is in motion from a sustained exercise, and the rate increases. Of course you measure it during exercise. The goal here is to stay within your Target HR Range or Zone, which is normally between 75% to 85% of your Maximum HR which is the third. Maximum HR is the rate at which your heart beats at 100% Max. during a sustained aerobic activity. You never want to work at 100% of your Max. HR unless a professional has you on a specific program designed for that, and your fitness level can sustain it. 100% of Max. will cause you to cross over into an Anaerobic Threshold. These numbers can vary depending on your age and fitness level. 


The Exercise Pulse is most accurately palpated at the larger Carotid Artery on the side of the neck. It is usually located beside the larynx. Place your index and middle fingers alongside the base of your ear lobe and slide it down to the side of your throat and apply a light pressure. DO NOT apply a heavy pressure to the Carotid Artery when measuring your Exercise HR. These arteries contain Baroreceptors that sense increases in pressure and will respond by slowing down your HR. You will feel this pulse easily during a workout, so heavy pressure is not needed to locate it. The Exercise HR should be taken for 10 seconds, always counting the first beat as "0," then multiply by 6. This number is your Exercise HR. Which brings me to the point of all of this information.
 




For Determining Your Max Heart Rate
 
To determine your Maximum HR, use the calculators below. The simple formula: Take 220 and minus your age which is accurate to approximately +15 BPM. You then take that number and multiply it by .75 - .85, which will give you your percentages of 75% -- 85% of your Max. HR. This is the Target Range or Zone that you want to stay in when doing any type of cardiovascular (aerobic) activity. When in this range your body is getting an optimum workout with maximum benefit, and it stays in a Fat Burning mode. 

There are two different ways to calculate your maximum heart rate and your target heart rates. The method I just explained is the simple method. 

Simple Target Heart Rate Calculator
Using the 220 - Age formula.

The Karvonnen formula is more advanced since it also takes into account your resting heart rate. This is your heart rate at complete rest. To determine this, take your pulse for 60 seconds just before you get out of bed... or take it for 30 seconds and multiply by 2

Advanced Target Heart Rate Calculator
Using the Karvonen Formula.

  • For your age, use a whole year. (Between 0 and 100)
  • Put your Resting Heart Rate in the next box. (Between 30 and 100)
  • In the % box, use a number between 50 and 85. Do not include the %.
  • Click on the Calculate button, and it will calculate your target heart rate or that percentage.

Your Target Heart Rate

When you start to work over these percentages, not unless you are in great shape and can push yourself into a higher range, then you have gone into an Anaerobic Threshold. Which means that you are pushing yourself way too hard, and no healthy benefits are being obtained. You are defeating your purpose. If you push yourself into an Anaerobic Threshold your body can no longer meet its demand for oxygen. You will start to feel exhausted, your HR increases above the Max. (which is 100%), you will stop the fat burning process, and you will start to hyperventilate due to the excessive amounts of lactic acid in your body. In other words, you are not pulling in enough clean oxygen through the lungs to clean it out of the blood. Your heart can no longer pump enough blood to your working muscles to sustain your activity, and you are overloading yourself. You prevent this from happening by staying in your Target HR Range. As you become more fit, you can push yourself into a higher range without going over into the Anaerobic Threshold. The purpose of this article is to give you insight to perceive that, and always know where you are in your range or zone when working out.

AN FYI
 
Remember that Aerobic means "with oxygen," and Anaerobic means "without oxygen." Aerobic exercise is training at a certain level of intensity for a sustained period of time, usually 20 minutes to 1 hour as on a stair-climber, treadmill, or in an aerobics class. You need oxygen rich blood to maintain this. 

Anaerobic exercise is training at a level of intensity that does not require a sustained period of time, usually 30 seconds to 1 minute. Such as weight training, strength circuit, circuit and interval training sessions when sets/reps are involved. Because the time period is shorter and faster in cases of intervals and circuits, you use all of the oxygen rich blood more quickly to complete your sets/reps before lactic acid causes you to stop the exercise. That's what "The Burn" means. Then you take a break so the blood can be cleaned of lactic acid and you catch your breath before your next set. 

One more element to consider is the Rating of Perceived Exertion Scale. This scale provides a standard means for evaluating your perception of your exercise intensity. You can use this scale on a 1 - 10 basis with 1 being "very very easy," and 10 being "very very hard." If you're like me, I don't like to stop during my aerobic exercise sessions to measure my HR, so I use this scale to measure where I am in my Target Range. I know how I feel at 75% -- 95% of my Maximum HR, so I can either increase or decrease my intensity before I cross over into an Anaerobic Threshold, and maintain my work out and Fat Burning process. If you are going to use this scale, make sure that you too know how you feel at 75% -- 85% of your Max. HR so that your perception is accurate on this scale.


Working out in the Target Zone helps me get lean!
(Editor's Note: This pic gets MY heart going.)

Knowing this simple information will help you greatly in evaluating your progress when training to get fit, or when training to compete. You can develop your training sessions and know what you need to change or add in your program by being in tune to your Heart Rate. Always be aware that you are in THE ZONE!

Train for Success!!!
